Hi Alian, I was trying to clone a 12 GB HDD on a dell machine to another machine of similar architecture but both of these are connected via multiple switches( 3 ) and these machines belong to the same network 192.168.17.0 I was able to do this cloning when there was only one switch between these 2 but when there are more than one switch UDPCast fails with Timeout problems and gives a message on the sender side that it is dropping client bacause of timeout. I am using Centercom FS708 swicthes in all the cases described above. Why is it failing for multiple switches?? is there are any workaround for this.
